Tell us what’s happening:

  1. You should use a template literal in your querySelector method.
  2. Your template literal should have the value ${targetId} .input-container.

Your code so far

<!-- file: index.html -->


/* file: script.js */
// User Editable Region

function addEntry() {
  const targetId = '#' + entryDropdown.value;
  const targetInputContainer = querySelector('${targetId} .input-container`);

// User Editable Region

/* file: styles.css */

Hi there. You have a single quote before the template literals block in the beginning. Instead, you need back tick on both end around the query selector’s value

Hi @harsya

Your querySelector is missing something before it.
Have a look at how you target other elements and selectors.

Happy coding
